EDIT: Granted, I also call the WHO "Who" and the GOP "Gop." And when I read "LOL" I hear "loll" in my head.
I do the "loll" thing too. When I'm typing lol or LOL I'm totally thinking loll never L-O-L. It's to the point that my brain basically accepts "loll" to be an interchangeable substitute for actually laughing out loud. Though sometimes I do actually laugh when I type lol, more often than not that gets represented as LOL.
And to close my case for loll, may I present lollerskates:
too scared to live; too scared to die
